Web1 Copper has a high melting point because of the strong electrostatic attraction between the positive ions and the ‘sea of electrons’. 2 Copper is malleable because the layers of atoms in the lattice can slide over each other. 3 Copper atoms can be oxidised to form copper ions by losing electrons. WebMore than a dozen experimental studies on oxygen self-diffusion in periclase have been performed over the last five decades (See Appendix – Table 1). Most of the early studies determined diffusion coefficients by measuring the rate of exchange of 18O with a gas phase, and relied on bulk measurements of the isotopic composition. phils vs cards
